False. The root of the Eukarya is probably within the Archaea, but this was only discovered six months ago. The consensus hasnt yet shifted from thinking the tree of life has three distinct domains. In any case, bacteria are a separate domain to Archaea.

Rachel Carson played a key role in the birth of environmentalism in the 20th century.
She became increasingly aware of the harmful facts of insecticide DDT on the environment. This compelled her to write her most famous work Silent Spring and defending herself against attacks from commercial interests.
The book also played an influential part in persuading governments to ban or heavily restrict the use of DDT and similar chemicals that persist in the environment.
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.
ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA.
iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.
Answer:
- The wind is caused by differences in air pressure.
- An anemometer is a tool for measuring wind speed.
- The wind-chill factor has a cooling effect
Explanation:
Winds move from areas of high pressure to areas of low pressure. This is because the areas of low pressure are composed of hotter and less dense air. The cooler air from the higher pressure region rushes in to displaces the rising warm less dense air. The direction from which the winds prevail FROM is used to name the winds(such as westerlies blow from West to East). A wind vane, windsock and anemometer measure the direction and speed of wind. As wind passes over the skin, it causes a cooling effect (the wind chill factor) because it blows the sweat away from the skin carrying with it the heat.
It will increase because of decreased photosynthesis. Photosynthesis uses carbon dioxide to function. So, the carbon dioxide levels would go up as the oxygen levels go down.
